Tools of the trade / Re: Cutting mylar stencils with a silohuette cameo
Interestingly enough, I'm having a hard time getting gerber2graphtec working with the Craft Robo Pro. It speaks GPGL just like the SD/Cameo, so that shouldn't be an issue. What's happening is it's feeding the page back out the front and asking to "Reload Media" after each stroke of the blade.

Yes, put it after gerber2graphtec.py, but add a space. (gerber2graphtec.py --force 10,20)

You want the first pass to be lower pressure, which will give you a more accurate shape as it will score on the first pass and actually do the cut on the second.

cut_mode 0 will increase precision at the expense of speed and 1 will sacrafice precision for the sake of a faster cut.

Here's where some of the info is located: https://github.com/pmonta/gerber2graphtec

The rest came from the command line:

timbmba:gerber2graphtec timb$ ./gerber2graphtec
usage: gerber2graphtec [options] paste.gbr >/dev/usb/lp0

options:
  --offset x,y        translate to device coordinates x,y (inches)
  --border bx,by      leave a border around the bounding box of the gerber file
  --matrix a,b,c,d    transform coordinates by [a b;c d]
  --speed s[,s2[,s3]] use speed s in device units; s2,s3 for multiple passes
  --force f[,f2[,f3]] use force f in device units; f2,f3 for multiple passes
  --cut_mode [0|1]    0 for highest accuracy (fine pitch), 1 for highest speed

defaults:
  --offset 4.0,0.5  suitable for letter size (portrait) on the Cameo, fed as "media" not "mat"
  --border 1,1      1-inch border in x and y around gerber bounding box
  --matrix 1,0,0,1  identity linear transform for scale and skew calibration
  --speed 2,2      use two passes, speed 2 in each pass
  --force 8,30      use force 8 for first pass, force 30 for second pass
  --cut_mode 0      highest accuracy

Oh, yeah you can set blade pressure with gerber2graphtec using the --force command.

 "--force f[,f2[,f3]] use force f in device units; f2,f3 for multiple passes"

So, --force 5,10,15 will do one pass at pressure 5, another at 10 and another at 15.

Edit: The default is a first pass at 8 and a second pass at 30.

Awesome, thanks for that Andre! I was wondering why it was re-homing the blade after every cut.

I got gerber2graphtec working (Mac OS X 10.8) on the Silhouette SD last night by simply adding the USB PID to the file. It cut beautifully! I'll give it a test on my CraftRobo Pro later this afternoon, but I don't see any reason it won't work.

Now, the CraftRobo actually has a parallel port on it in addition to USB, so I'm wondering if I could hook a print server to it for wireless printing. It's a JetDirect, so that should be a RAW transport...

Yeah, I know it won't hurt it, but that's her baby, I'm sure you know how that is. She got a Cameo to upgrade from her SD a few months back. If I can do this with her old SD I'd rather use that than my CraftRobo Pro, since I just don't have the space to keep the latter on my desk all the time, but the SD is small enough I can make a spot for it.

I'm on OS X, but can use Linux (via VM or my R.Pi) or Windows (VM or old laptop) if I need to.

I've already got lots of those transparencies and various types of vinyl, I was just curious about specific places to get Kapton.

Anyone tried this with a CraftRobo Pro? I picked one up a few years back to do die cut decals with and actually thought about cutting solder masks a few weeks ago but got discouraged by some guys on another forum (it'll never be precise enough, you have to use a laser cutter, etc). Now that I see this thread I think I'll give it a go.

The CraftRobo Pro is Graphtec's higher end cutting tool. It has a bigger cutting area, higher cutting force and the ability to feed from rolls, along with the standard features of reading registration marks and speaking the Graphtec language.

My fiancé has both a Cameo and SD as well and said I could try it with the SD but the Cameo was off limits (scrapbooker's are protective of their tools, god forbid you ever use their scissors).

Where do you guys get the plastic at?
